摘　　要：针对当前时空数据挖掘中常用数据模型具有较强应用指向性,通用性不强的问题,基于面向对象建模的思想,提出一种属性特征与时空关系一体化的时空数据模型,定义并详细给出了该模型的元素组成、信息范畴及元素间的相互关系,并以城市规划中地区建设变化为例验证此数据模型的有效性。Currently,the common data model of the spatial-temporal data mining has the strong application directive property and low general applied capability.Be aimed at this question,a spatial-temporal data model which inte- grated attributes and relations between the space and time was proposed based on the object-oriented modeling thought.The components,the information category and the relations of each components were defined and particu- larized.Finally,the paper validated the data model in changes of urban pla...
